1.	Assertion (A): Pure H_(2)SO_(4) is colourless. Reason (R): On long standing H_(2)SO_(4) undergoes decomposition to form SO_(2).
Answer» Both A and R are true and R is CORRECT EXPLANATION for A. Both A and R are true but R is not the correct for A. A is true and R is false. Both A and R are false. Solution :Pure `H_(2)SO_(4)` is COLOURLESS. `H_(2)SO_(4)` is a stable ACID. HENCE it does not undergo decomposition on long standing.
